To all who-1h it may concern:

citizen of the United States, residing at Hopedalc in the county oiv Woroester and State of Massachusetts, have invented certain" new and useful Improvements in Thread-Porter Mechanisms; and I do here by declare the following to be 2. full, clear, and exact description of the invention, such as will enable others skilled in the art to which it spperteins to make and use the same.

The present invention relates to en im; provement in thread porter inechwisins for looms.

The object of the invention is to produce a thread porter mechanism of such construction and arrangement oi parts that any fill ing end extending outwardly from the eelvsge for a, substantial distance will be engeged and severed relatively close to the selvsge. To theeccomplishment of time ohject and such other OhJeotS as shall 'hereln after appear the present mvention consists es in the improved thread porter mechanism described in the following specification and particularly pointed out, in the appended claims.

The preferred form'iu which it iseontema 3o plated embodying the invention s illustrsted in the accompanying drswmgs, in which F i re 1 is e, perspective View of u. portion 0% a looni'showing the epphoution oi the im roved thread perter mechanism as thereto; F zg. 2 is n, plan of the pertsshown in Fig. 1; and Fig. 3 is e diegremmetlc view showing the improved thresd perter mesh enism located beside each selvage.

The usual temples 11 are secured to the breast beam 6 to hes the woven cloth 12 stretched taut loterall These parts are familiar to those skille in the art and perform their usual functions. i

The improved thread parter mechsnism' comprises a horizontally disposed elongated thread support 14 which is arranged along beside the salvage or outer threads of the warp 15 and substantially parallel with or slightly below the plane of the woven. cloth 12, or the unreised section 16 of the welf'lp' threads This thread support 1% exten s forwardly beyond the fell 9, and rearwerdly to the limit of the rearward movement at the lay, and its srrsngement is such that any filling end of substantial length extending outwardly from the selvage will be support- I ed. in-position to be acted on and severed by a thread porter located between the thread a support '14 and the salvage. For convenience of illustration, the usual temple cutter 18 is shown for performing. the thread severing operation. for as isknown, it has not heretofore been proposed to provide means for severin close to the selvege all filling ends exten ing outwardly from the selvage. The difliculty has been to support the filling end imposition to he acted upon by the thread. parting means. It is known, of course, that it has been proposed to sup port in various ways the outgoingfillingend extending from the salvage to the critically exhausted bobbin but only in feeler looms), and the incoming filling end extending from the hopper to the selvage, so that they may he severed close to the salvage; but so far as is known, however, all these prior vices are adapted only for action upon outgoing and incoming filling ends, and cannot set on adventitious filling endsextending locyond the selvage.

The thread support 14 is conveniently supported at its'forward end by the 100m temple, and at its rear end by an arc-she ed For the, purthe thread support 1% from being whipped out of thread severing position by the draught created by the lay in its backward and forward movements, a thread guard 23 is provided, which is also supported at its forward end by the temple, and at its rear end by the resilient piece 19, as shown in Fig. 1. It will be observed that the thread. support 1 and the thread guard 23 approach quite closely together opposite the fell and may aptly be said to constitute a false shed. This arrangement aidsmaterially in keeping the filling end in position to be acted on by the thread parter. It will also be observed that at their rear ends the thread support and the thread guard are separated a distance somewhat greater than the depth of the shuttle, and are so arranged that the shuttle may pass freely between them. The thread support 14, the thread guard 23 and the piece 19 are all construct ed of resilient material so that in case the shuttle should stop between these parts, no breakage will result on the subsequent beatup' of the lay.

lhe great advantage resulting from the present construction of thread p'arter meclr a'nism lies in the fact that all filling ends extending outwardly from the selvage are severed close to the selvage, Whether these filling ends are the outgoing and incoming filling ends or whether they are left by the shuttle when the filling, therein entirely exhausts or breaks. This fact makes it possible to locate the thread parter mechanism on the side of the loom opposite to that on which the weft replenishing mechanism, indicated at 24, is located. So far as is known, it has not heretofore been proposed to locate a thread p'arter mechanism on the sidefo'f the loom Opposite to that on which the Weft replenishing mechanism is located. The advantage of this arrangement is obvious. If

the filling entirely exhausts or breaks on the fiight of the shuttle toward this side of the loom, and a filling end left extending outwardly from the selvageg'; this filling end Will be severed close to the selvage. The same advantage holds whenthe thread parter mechanism is located on the replenishing side of the loom, becausedn that case also, if the filling entirely exhausts or breaks on the flight of the shuttle toward the re plenishing mechanism and the 'filling end extends beyond the sel'vage, it will be severed close to the selvage. This has not been possible heretofore, because the thread parter mechanisms usually located on the Wett'replenishing side ofthe loomare not adapted to act upon a filling end left by a completely exhausted shuttle, unless perchance the fillipg end is long enough to extend to the shut i1 8.;

It will be understood from the foregoing description that the thread parter mechanism lessees of the resent invention is equally applicable to 0th plain and automatic looms, and to both filling feeler controlled and filling detector controlled replenishing looms.

Having thus described the invention, What I claim is:

1. A thread parter mechanism for looms having, in combination, a thread support located close to the selvage and substantially in the plane thereof, said thread support extending from the fell rearwardly a distance substantially equal to the. length of the throw of the lay, and a thread parter located between the selvage and the thread sup port.

2. A thread parter mechanism for looms having, in combination, a thread parter for severing the filling; ends supported in position alongside of and close to the selvage of the cloth being Woven, and a thread support located immediately adjacent to the parter, and therefore located close to the selvage, for supporting, in a position to be engaged and severed by the'parter, the filling ends extending outwardly an appreciable dis tance from the selvage,

A thread par'ter mechanism for looms having, in combination, a thread support, a stationary thread guard, said members be ing relatively close together opposite the fell and relatively far apart at the limit of the rearward movement of the lay and being arranged so that the shuttle passes between them in its flight, and a thread parter to cooperate with the thread support and the thread guard to sever a filling end extendsing outwardly from the selvage.

4. A thread parter mechanism for looms having, in combination, a thread parter for severing the filling ends close to the selvage,

and thread supporting means for supportin the filling ends in a position to be engaged by the thread parter, said. thread supporting means beingpositioned in such proximity to the selvage that the fiexural strength of the filling" ends supported thereby will permit them to be loosely supported in a-substan- 'tially horizontal position.

5; A thread parter mechanism for looms having, in combination, a thread support arranged to support a filling end extending outwardly from the selvage, a stationary thread guard arranged above the thread support to prevent the filling end from being displaced, said support and guard extending between the dents of the reed, and a thread parter to sever the filling end close to the selvage.

' .6. A thread parter mechanism for looms having, in combination, a thread support and a thread guard. mounted on a stationary part of the loom, located beside the selvage and arranged for the passage of the shuttle between them, and having substantially the same relation to each other as the upper and Mill lower sections of warp threads have when the shed is open, and a thread parter located between the thread support and the selvage.

7. A thread parter mechanism for looms having, in combination, a thread support and a thread guard, angularly arranged with relation to each other and so that the shuttle may ass between them, means adjustable longitudinally of the lay for sup-- porting the thread support and the thread guard, and a thread parter.

8. A loom havingyin combination, weaving devices, a thread parter for severing the filling ends supported in position alongside of and close to bothselvages of the cloth 'being proven, and a thread support located immediately adjacent to each part/er, and

therefore located close to the selvages, for

supporting, in a position to be engaged and severed by the )arter, the filling ends extending outwardly an appreciable distance from the selvages.

9. In an automatic filling replenishing loom comprising transferring mechanism and means for parting the fillingend leading to the filling carrier to be discharged; guiding means permanently anchored to oppesite sides of the loom frame at opposite sides of the path of the lay and extending acrom the lay during its entire beat-up above the path of the filling and operating to direct the filling end into the field of the part-' ing means upon transfer.

10. In an automatic filling replenishing loom comprising transferring mechanism and means for parting the filling end leading to the filling carrier to be discharged; guiding means permanently anchored to opposite sides of the loom frame at opposite sides of the path of the lay and extending across the lav both above and beneath the path of the filling and operating to direct the filling end into the field of the parting means upon transfer.

11. In an automatic filling replenishing loom comprising transferring mechanism and means for parting the filling end leading to the filling carrier to be discharged;

' the layheneath the path of the filling end and operating to direct the filling end into the jaws of the filling end parting means.

13. A-e-loom having, in combination, weavingdevices including a lay, a temple thread parter, and a supporting member secured upon the temple and extended transversely across the lay, said supportin member being adapted to su port short ling ends extended laterally roin the selvage to facilitate the severance thereof by the temple thread part/er vlet. A; loom having, in combination, weav-r ing devices, a thread parter mechanism 10- cated close to one selvage and a false shed located close to the selvage and comprising two members arranged in the planes of the open shed to permit the passage of the shuttle therebetween.
